TOP.

OHIO, ASSIGNOR TO THE GIBBS MANUFACTUBfifi' COMPANY, or CANTON, OHIO, A CORPORATION or 0H10 Specification of Letters Patent.

Patented. Oct. *7, 1919.

To all whom it may concern: 7

Be it known that I, ELMER W. GIBBS, a citizen of the United States, residing at Canton, in the county .of Stark and State of Ohio, have invented a new and useful Top, of which the following is a specification.

The invention relates to the construction of tops and twisting heads for tops of the type shown in Letters Patent No. 847,933, issued to me on March 19, 1907, and Letters Patent No. 1,005,020, issued to me on October 3, 1911; and the improvements include the making of a light but strong and durable top and head out of sheet metal in an economical manner, the head being so constructed that the twisting spring is mounted and secured in such manner that it cannot become accidentally displaced from the head. 7

'The objects of the invention are to construct a top and twisting head of sheet metal, in which the parts will be stron and durable and economically constructe. and

to generally improve and simplify devices of the character disclosed in my patents above mentioned.

With these objects in view the invention consists in the novel construction and arrangement of parts, hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions,

size and minor details of construotion'may' be made within the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages of the inventlon.

The invention thus set forth in general terms is illustrated in the accompanying drawings forming part hereof, in which- I Figure 1 is a side elevation of a top with the twisting head thereon;

Fig. 2, a vertical section of the same; Fig. 8, a plan view of the top with the twisting head removed;

Fig. l, a lower end View of the twisting head; I a Fig. 5, a perspective view of the several parts of the twisting head in position for assembling; and

p 6, a perspective view of the stem of the top.

A practical embodiment of the invention is disclosed in the accompanying drawing, forming a part of this specification, in which similar numerals of reference indicate corresponding parts throughout 9 the several views. 7

The twisting head 1 is composed of the case members 2 and 3, the disk partition-4c,

the twisting spring 5, the spring barrel 6,

the locking pin 7 and the locking spring 8 which parts are separately made,preferably as illustrated in Fig. 5, and are then assembled to form the completed head as shown in Fig. 2.

The case members 2 and 3 are shaped or stamped out of sheet metal in the form of cylindric cups, the rim of the member 3 being provided with the lip flange 9 and the rim of the member 2 being provided with the rabbet flange 10 adapted to telescope over and then'be bent over the lip flange to form the completed case, as shown in Figs. 1 and 2.

The closed or outer end of the case mem-v ber 2 is provided with the concentric opening 11, having the inturned annular'flange 12 bent inward therefrom to receive the stem of the top as will be later described; and the closed or outer end of the case member 3 is provided with an aperture 13 having a similar inturned annular flange 14L arranged to receive the lower extremity of the spring barrel 6'.

The transverse disk partition l is provided in the case wherein its edges are clamped and secured between the flanges of the case member when thesame are engage together as shown in Fig. 2. This partition is providedvwith the central aperture 15 through which the spring barrel 6 extends, and a radial slot 16, communicating with said central aperture, to receive the radial projecting portion 17 of the spring barrel to prevent rotation of said spring barrel. A lateral aperture 18 is provided in the disk which with the similar aperture 19 in the end of the lower case member constitute guides in which the locking pin 7 is located and adapted to operate endwise. V

The disk'partition is preferably provided around its periphery with the deflected tongues 20 which may be cut'in the periphcry and are arranged to engage in the notches 21 provided in the lip flange 90f the lower case member, thus serving to stop the case member against rotation with relation to the case of the twisting head.- 1

The locking pin 7 is provided with the stop flange 22 near its lower projecting end, which normally abuts the lower end of the case, between which flange and the trans verse partition is located the locking spring 8, which is preferably in the form of a spiral extending around the pin and byits energy servesto hold the pin in its normal clownward projecting position. For the purposes ofthe locking pin and its frame it will be understood that the end of the case and the transverse partition may be collectively considered as cross walls. I The spring barrel 6 is composed of sheet metal, the ends of which are bent radially 'asshown at 17, the spring 5 being contained within said barrel, the upper end of the spring extending through the notch 23 and provided with an eye 24, a pin 25 being passed through said eye and through the registering aperture 26 in the out-turned car 27 formed upon the upper end of one of the radial portions 17. A projecting hook 28 is provided. upon the lower end of the spring and projects beyond the barrel and lower case member and is adapted to releasably engage in the recesses'or sockets 29,. which are provided for that purpose in the upper end of the top. -The spring barrel is mounted between the outer or closed ends ofthe casememberathe upper end of said barrel bearing against the upper end of the case, while the lower end of the cylindrical portion of the barrel projects through the aperture 13in the lower wall of the case,

, the radial-portion 17 ofthe barrel, which is slightly vshorter than the cylindrical portion,

7. engaging the bottom wall of-the case.

; It is evident thatby this construction and arrangement of the parts a better and more eflicient twisting. head is produced than is disclosed in either of my prior patents above referred to as the secured end'of the spring does not project outside the corresponding end of the case nor does the fastening means forjthe securing end of the spring project outside ofthe case and there is therefore no T danger of cuttingor injuring the hand of "the user by the breaking or disconnecting of this end-of the spring nor is there danger -of this end of the spring becoming discon necte'd as the entire spring and connecting imeans, with the exception of the projecting hook 28, iscarrieol within the case. A simple I but substantial twisting head is thus made which is well adapted to the purpose of spinning the top, whichoperation will be later described Thetop comprises'the upper and lower lconcaved members 30 and 31 respectively,

upon the adjoining edges'of the two sectlons. The upper section is provided with the raised portion 34 which receivesthe disk 35 forming an air chamber 36 between the disk and the top surface of the raised portion 34, a practically air tight joint being produced between the disk and the inner surface of the top, thus cuttingioff the inflow of air into the interior of the top.

The upper surface of the raised portion 34 is provided with the apertures or sockets 29 and with the curved indentations or slots 37 inclined tongues 38 being located in said slots. Thestem 39 is preferably formed of sheet'metal of cylindrical form, the upper n end thereof having cusps 40 formed thereon,

which are bent as shown in Figs. 2 and'j6 lforming an upper rounded closed en'dfor the stem. The lower end of the stem is open and rests within the I socket-41 formed .in

the lower member of the top, the head of the 39 and is held in tight engagement with the inner surface, of the raised portion 34 by means of the peripheralrib 44 formed-upon the stem. This disk 35 is provided with a concave as shown at 46 for purposes l of strengthening the disk and allowing it to be forced into tight engagement with the inner surfaceof the raised portion 34 -without bending'of the disk.

V For the purpose of producing a humming top the lower section 31 is provided with thefapertures47 andrin order to" produce a' humming sound the inflow of air into the top body must be cut ofli and for this purpose the -disk35 is so mounted within the top that practically air tight joint is formed between the disk and I the inner vwall of the-top.f v 7 a i The operation of the top may be briefly described'as follows: The stem'39 of the top is inserted from the lower end upward through the hollow of the twisting spring as best shown in ,Fig. 2, and the projecting hook 28. on the lower end of the spring is engaged with one of tthe'recesses' 29 r in the upper surface of the top The head is then rotated to twist the springin which operation the looking pin successively enters and engages as a ratchet in the inclined recesses '37, the

resilience of the locking spring'8 permitting the-spring to ride over the intervening faces 48 of the top. V c

When; the spring has been suflicientlytwisu ed; thetop isspun as by merely holding the sides "of the twisting head between the i v first two fingers and pressingthe'stem downwhich are connected 'together'by means of ward with the thumb which serves to' disengage the locking spring the: top

reinforcing corrugation45 and is preferably and permits the twisting spring to unwind itself in doing which it rapidly rotates the top with the stem thereof as an axle in the twisting spring, until the hooked end of the stem is disengaged from the top recess after which the head is lifted from the stem of the top or the stem of the top drops out of the head.

It will be noted that the barrel 6 not only holds the fixed end of the twisting spring 5 against movement with relation to the twisting head but also tends to keep the twisting spring in alinement preventing any buckling of the twisting spring.
